'Center' in the Bible

"This is what the Lord GOD says, "This is Jerusalem. I placed her in the center of nations, with many nations surrounding her.

Therefore this is what the Lord GOD says, "Because all of you have become dross, watch out! I'm going to gather all of you at the center of Jerusalem,

just like a smelter gathers all the silver, bronze, lead, and tin to the center of a furnace and injects fire in order to melt it, I'm going to gather you in my anger and rage, make you settle down and then I'm going to melt you down.

like melting silver at the center of a furnace. When you've been melted from the center out, then you'll know that I am the LORD. I'll pour out my anger on you.'"

I'm going to confiscate anything I can put my hands on. I'll attack the restored ruins and the people who have been gathered together from the nations, who are acquiring livestock and other goods, and who live at the center of the world's attention."
